Premier African Minerals Limited (LON:PREM) has raised just over £262,000 from a crowdfunding round.
Shares were sold at 0.1p, with the money earmarked for its Zimbabwe tungsten and lithium operations.
George Roach, chief executive, added that delays to electrification work at the RHA tungsten mine due to currency issues holding up parts means the re-start will be in 2020.
At Zulu, the outstanding requirements for an exploration permit are now also procedural, he said, including the sign-off from the President.
Premier remains ready to mobilise as soon this sign-off on the EPO is granted and to continue discussions with those parties who had expressed an interest in participating in Zulu, Roach said.
